“Greetings from Captain John. There will be no swimming and no diving.” Sailing on the Frieze ferry to Randall’s Island, the driver told us that we were on our way to vacation, but cautioned against letting loose with freewheeling abandon. Once we landed, that ethos seemed to be in effect at the fair itself: dealers and collectors were having fun, and the fair was certainly crowded, but nobody was breaking out champagne in the early afternoon to celebrate skyrocketing sales.
